MACHlNE- FOR CUTTING WASHERS.

SPECIFICATION forming part of Letters Patent No. 507,210, dated October24, 1893.

Application filed June 20, 1893. $erial No. 478,238- (No model.)

To aZZ whom it may concern.-

Be it known that I, AUGUST BUOHHOLZ, a citizen of the United States,residing at Boeuf Creek, in the county of Franklin and State ofMissouri, have invented certain new and useful Improvements in Machinesfor Cutting LeatherWashers and I do hereby declare that the following isa full, clear, and exact description of the same, reference being had tothe annexed drawings, making a part of this specification, and to theletters of reference marked thereon.

The present invention has for its object to provide a simple andpractically operating machine for cutting washers from leather, one thatwill perfectly cut the washer without leaving any ragged edges and cutwashers of different sizes and the machine controlled by the operatorwhile in an upright position or sitting down, also constructing theoperating parts in such manner as will insure strength and durabilityand not become inoperative for reason of the parts getting out oforder.These several objects above enumerated I attain by a machine constructedsubstantially as shown in the drawings and hereinafter described andclaimed.

Figure 1 of the drawings represents a side elevation of my improvedmachine partly in section; Fig. 2 a part sectional elevation on anenlarged scale of the base of the machine and that portion carrying thecutters; Fig. 3 a horizontal sectional view thereof taken on line w 00of Fig. 2 Fig. 4 a detail view of the cylinder showing the scale andkey.

In the accompanying drawings A represents a standard or frame whichsupports the operating parts of the machine, said standard being of anysuitable form and construction and of any desirable size and cast orotherwise formed of metal.

. The standard A is provided with a base B for supporting a bed 0, whichbed is pivotally connected to the base by means of a screw or andthumb-nutb so that the bed may be swung around laterally to obtainaccess to the opening 0 in the base, to clean it or for any otherpurpose found necessary. A block is provided which may be of anysuitable thickness and shape, said block resting upon the bed 0 andhaving a pad d of leather Q or other similar material, and upon this padrests the leather from which the washers are to be cut. This block D isrendered adj ustable by means of the set-screw e and slot f so as tobring the pad d directly under the cutters. An adjustable gage E isprovided which is bifurcated or semicircular in shape and is renderedadjustable by means of the screw a and the set-screw t' which extendthrough slots in the gage. This gage E acts also as a guide to steadythe cylinder F in its vertical movement, as well as acting as a stop forthe leather when placed upon the cushion or pad d, said gage havinggrooves is with which engage the guide-rods Z, said .rods being rigidlyconnected to the cylinder F and to a cross-bar m. The cross-bar m isloosely supported upon the lower end of the shaft G in any suitablemanner so that the shaft can turn without interfering with the cross-barwhich latter remains stationary after the cylinder is forced down intoposition upon the leather. The cutter-head H has connected to it aplurality of cutters or knives I, which knives are of any suitable formand construction and adjustably connected to the cutter-head in anypreferred manner. The knives are both vertically and horizontallyadjustable, or rather have a compound adjustment so as to adjust thewidth of the washer to be cut and also to adapt the height of the knivesto the vertical movement of the cutter-head.

The knives I are adjustable vertically by means of the screws n or otherwell known means may be employed, and the horizontal adjustment of theknives is effected by the screw-rods K.

I do not wish to be understood as limiting myself to the means shown ofrending the compound adjustment of the knives as any desirable'and wellknown means may be employed that will enable the knives to be properlyadjusted in a vertical and horizontal direction and also to enable theknives to be removed when found necessary.

The cutter-head H has a chambered shank L in which is located a spiralspring M, and within the chambered shank is also located the stem 0 of apresser-plate N having suitable openings 19 through which the ends ofthe knives I extend when in the act of cutting the leather. Thepresser-plate N has a centering spur i" which enters the pad (I when theplate is pressed down thereon, and to enable the plate to be operatedindependently of the cutter-head H, the stem 0 is formed with slots 8 sothat the movement of the stem will not interfere with the adjustingscrews K, and the shank L has slots 15 through which the pin 11. extendsto hold the stem of the presser-plate within the chamber of the shankand enabling it to move vertically independently of the cuttenhead andshank.

The shank L of the cutter-head H is detachably connected to the shaftGin any suitable manner or as shown in the drawings, and above thecross-bar m and adjustable collar o, is located a spiral spring 0. Abovethe collar '0 and to the shaft G is connected a hand-wheel P foroperating the machine when sitting down and when standing up a lever Q isprovided for this purpose which handlever is pivoted to the standard Aat its upper end and to a supplemental shaft R, the lower end of thesupplemental shaft serving as a plunger to force the main shaft Gdownward but does not turn in its bearings.

The shaft G and also the plunger-shaft B have their hearings in thestandard A, and connected to the shaft G is a bevel gear-wheel S withwhich meshes a pinion T upon the end of a horizontal shaft W, whichshaft also has its hearings in the standard and is provided at its outerend with a belt-pulley U of any of the usual forms.

Through the medium of the belt and pulley, motion is imparted to thehorizontal shaft W, and through the gear connection with the shaft G,the latter mentioned shaft is rotated and carries with it thecutter-head II and knives I. By means of the feather on the bevelgear-wheel Sand the longitudinal groove in the shaft G, the shaft isenabled to have a vertical motion without interfering with the gearwheel. Through the medium of either the hand-wheel or lever, the cutterhead with its knives is forced down and brought into position for theknives to operate. The presserplate and cylinder are now moved down intoposition and the cutting of the washers takes place, the springs O Vupon the shafts G R respectively, forcing them up to their normalposition as the pressure is removed from the hand wheel or lever. Thecylinder F has an opening w on line with the screw-rods K when thelatter are brought around to register therewith, and around the openingis a suitable scale as shown in Fig. 4. A suitable key Y having apointer y is used to adjust the screw rods so that the knives will beset to cut washers of any given circumference, the pointer upon thescale or dial indicating the circumference or size of the washer to becut.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

1. In a machine for cutting leather washers, a suitable standard, arotatable shaft, carrying a hand wheel knives for cutting the washersconnecting with the shaft, and a supplemental shaft or plunger and meansconnected thereto for forcing down the main shaft, substantially as andfor the purpose set forth.

2. In a machine for cuttingleather washers, the horizontally adjustablescrew-rods and a slotted shaft by which they may be verticallyadjustable, and adjustable knives engaging the screw threads upon therods, substantially as and for the purpose specified.

3. In a machine for cutting leather washers, a suitable standard, arotatable and vertically movable shaft and knives connected therewith, apivoted bed, an adjustable block having a pad connected thereto, andadjustable gages connecting with the bed, substantially as and for thepurpose described.

4. In a machine for cuttingleather washers, a rotatable shaft havingavertical movement in its bearings, a cutter-head connected to theshaft, knives adjustably connected to the cutter-head, an independentlyoperating pressure-plate,and an independentlyoperating cylinderinclosing the cutter-head, knives, and presser plate, substantially asand for the purpose specified.

5. In a machine for cutting leather washers, screw-rods carrying cuttersadjustable thereon, a cylinder inclosing the cutters and having akey-opening and scale around it, and a key with pointer for turning thescrew-rods and indicating the position of thecutters, substantially asand for the purpose set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
